METHOD OF SEAMENG (JAN HEADS TO CAN BODIES.

APPLIUATION FILED JUNE 19, 1909. W6 0 Patentd NOV, 22,1910.

2 SHEETSr-SHEET 2v A TTORNEYS- the tongue 7 will form an inwardly-projecting part of the layer 5, as shown in Fig. 5. To make sure of the tightness of the joint, the fold may be doubled, as shown in Fig. 7, in which the head flange 6, as shown in Fig.

. 2, is replaced by a new fold. To assure the other in the lower die of the press, and the resulting seam has a layer 12 jammed in extra fold desired, the flange of the can body is extended upwardly, as shown in Fig. 8, between the inner and outer flanges of'the cover.

The can body and head are made as shown in Fig. 8, and are placed upon each fold is formed as soon as the members 9 and 10, constituting the upper die, descend. The

between the extended layers l and 14 of the layer'5. The layer 1d maybe single or otherwise if desired.

In producing the seam shown in Fig. 9, the spring-pressed plunger of the press may be avoided and a solid male die 9 used. In this seam the double edge and 5of the head is ammed in between the inner double layers 2 and 15 and the outer layer 16 of the folded edge of the can body. In this case the can body and head are formed with the edge flan es, as shown in Fig. 10, and the seam finished by the descent of the upper die 9 alone.

Having thus described our invention, we claim as .new and desire to secure by Letters Patent:

The herein-described process of seaming a can body with a can head, which consists in providing both the body and head with edge flanges such that they may be freely moved one within the other'and the flange of the head seated on the flange'of'the body, then by a single operation iamniing the flanges together to bind a'doub e layer of'one flange between a fold in the other flange.

In testimony whereof we have signed our names to this specification in the presence of two subscribing Witnesses.
